MORALES OJEDA, Miguel et al. Pressure ulcers: risk, predisposing factors and hospital prognosis in patients older than 65 years. Rev. virtual Soc. Parag. Med. Int. [online]. 2021, vol.8, n.2, pp.23-33. ISSN 2312-3893.


Pressure ulcers (PUs) drastically influence the hospital stay, causing discomfort and pain to patients.


To determine the risk of developing PUs and jointly evaluate nutrition / diet and degree of independence in patients over 65 years of age.


Descriptive and cross-sectional design. Four hundred and forty-four patients with and without PUs, admitted to the Silvestre Adventist Hospital, Rio de Janeiro, Brazil between 2018 and 2019, were evaluated using the Braden Scale, the Mini Nutritional Assessment Short Form and the Prisma 7.


Regarding the Braden Scale, the group with the highest representation was the Moderate Risk of suffering Pus (37.6%). The group stratification of Prima 7 showed two main groups, the largest (51.8%) corresponding to positive Prism (> 3), followed by the negative Prism group (35.1%). According to the Mini Nutritional Assessment Short scale, 41.9% of hospitalized patients were at risk of malnutrition and 34% were malnourished.


The study related PUs to a series of factors such as malnutrition, immobility and loss of independence. The Braden scale proved to be a good predictor of UPP. It was evidenced that PUs are a highly prevalent problem in the hospital, and that multidisciplinary support for the care and treatment of these injuries is essential.
